To all whom t may concern c Be it known that I, CHARLns'L. Heisman,

a citizen of'the United` States, residing at Schenectady, in the county of Schenectady `and Stateo-f New York, have invented certain new and useful Improvements in Locomotive-Sand-Box Arrangements, of which the following is a specification. l

My invention relates to an improved form ofair, and hand, track sanding device, such as generally applied to locomotives; and has for itsI objects: First z--the reduction in the cost of manufacture; by permitting the entire air and hand sanding arrangement, with the necessary air pipes a-nd Voperating levers, tobe made up in lots, and thereafter to be attached to any size of a simple form .of sandbox casing. y casting .in small parts Ithe Aseveral vsand valve, ports, and more intricate pieces; also to simplify the molding of the large sand box casing by omitting all the intricatecorework and instead ycasting it in the small pieces., Third to-.siinplify the ordering of castings, and the making of drawings for changes in type of- Sanders, all of which can bereadily attached to the simple Aform ofcasing without change of pattern or drawings, Fonrth z-to simplify the cost of maintenance bythe, use of a-siniple design of sand-box, or-casing, to which anyform of sander may be attached. in a few 'mo. ments time. Fifth to provide a combined air, and hand, sander with a single sand outlet arranged in commonto both and s0 that 'the hand sander valve lever may be used .to clear a clogged inlet free of pebbles, or other debris, without the necessity of using a wrench and poker. SiXth: -to pijo-4 vide an anticlogging sander which cannot become inoperative, even temporarily,l by the Apresence of debris in the' sand. Seventha-to increase the available sand holding capacity of the casing or boX, by

means whichl will cause each air sander vto collect the sand 'from a large-area ofthe sand-box bottoni, instead of at a single point. as in the older devices, whichmake available for sanding only a comparatively small portionof the sand in the box With'- out -again re-distribnting the sand-With a shovel.

Fig. 15 `shows the same box as in Fig. 1, with the sand valve'a'rranged on elongated air-blast sand tubes, instead o'f the lshort airvblast tube or funnel' formed in the valve shown in Figsfl, 2 and 3'.

Numerals 1', 1a and 11 1n and 15, show the dome like casingI of the sand-box which differs from those of' usualconstruction in that it 4is Yprovided with two `circular openings 2, 2t, 2b, 2, and 2d, shown in Figs. 1, 2, 9, 13 `and 15.' The com.moii

axis of theseft-wo circulart openings is preferably short distance above the bottom of `the sand-box so' they can bev bored at vone setting `by means of a boring bar passingthrough both openings. Lu'gs 3, 3, 3F, 3, 3d, 3", are cast on the casing of the b'oX 'and illustrated, These fcircular openings permit the attachment of vany desirable form Specvicaton of Letters Patent.

4100 A project toward the center ofthe openings to vlois of sander, and,'a.s s'h'o'vvn,"re wellsuited for the" improved' type' of air, and hand sander to bey hereinafter described. v The arrangement for :hand 'sandingj conu .sists'ofa crank shaft 5f, 54, arranged 1 withinpthe casing, .I, land supported by 'bear- 'G' 6'5, 6j", .6?, Gf, formed vin the valve flanges, and which is oscillated from the cab by means ofa iod, -in the usual manner for the purpose of swinging the double ported valve 7, 7 a, 7 3, 7 c, 7?, 7 e, 7 f, away from its normal, or mid position, shown in the lig-lires, and thereby; permit the sand to owinto" the discharge Pipe; 8, sa' 8b" 8% Sdi 8e Lthat carries it to the corresponding driver valve tight wheel'of the locomotive. A

pin, 9, 9, passes through the crank shaftand engages with a slot, 1 0, 10a, in the valve. 'This construction permits thespring y11, 11, Fig. 1, to hold the against the flange and prevent leakage, at the same time the pin compels it torotate with the shaft. For protection thespring is pocketed in therecessed hub of the valve. .In Figs. 1, 2, 3, 4, 5, .6, 7, and 13, a

pairoffsliort air` sand blast tubes, funnels A or hoods 13, 13, 13", arecast directly in the .-10 and 11, and arrange 'the-valve with an adjustment forlow by means of the small slidelftarranged over i slot 15 formed in the yvalve as shown in Figs. 8, 10 and 12.

- ATo rovide a means ejecting practically a l the sand from the box the air sand blasttube's 13 are extended inwardly and radially if desired, as shown in'Figs. 14 and'l 15. A slot, or

port, 16, 16"', 16g, iscut into the top of the tube near the ange, and is covered by the valve 7", 7, as shown in. Fig. 15.` Elongated sand inlet port or ports 17, 17, 17", 17e, are arranged in the tube as shownin Figs. 15 and 17 either atthe sides or in the bottom. This arrangement of sand inlet' ports causes thesand to flow from an extended area of the box to within reach of the airjet'which blows it down the corresponding discharge pipe 8c or 8d.

f y' The arrangement permits the independent use of either the hand sanding device, or air sander, which'make common use of a single discharge pipe. The elongated sand inlet ports 17,17% 17", and 17',` prevent pebbles from clogging the flow, as the sand will continue to flow into'the tube from either side of the clogged section, as'proved in practice; which also shows that the operation is not in vthe least interrupted when sections of the tube are uncovered. Iflfhe several modifications show that` all the mechanism can uickly and easily beapplied or removed ill-om the casing. It can be arranged for single, double (as shown), or triple Sanders and with any combination of single, or double lhand sander. The device can evidently be attached to other formsof cas or' sand boxes having at9i'11.01me bottoms.

The air'pipes 1S, 18a, 18", are preferably passed through the valve anges 4, 4, 4",

etc., to' avoid drilling 'the casing. Brackets 19, 19, cast on the flange hold the nozzles 12, 12?, 1n proper position with respect to the dlscharg'e sand out-let. The inclined crank shafts'b of thetwin boxes in Fig. 13,

.'may have clogged the air jet or outlet, by

merely' actuating the hand sa-nding'crank shaft 5 1n the usual manner; thereby saving --the labor and annoyance of clearing the noz- .zle by loosening'a plug and using a poker. W hat I claim 1s:
